A well-graded driveway is essential for effective water drainage, long-lasting surface integrity, and safe access to your property. At Geelong Road Tech, we often see driveways around Geelong, VIC affected by inadequate grading — an issue that can lead to premature deterioration and costly repairs if not addressed early.
So, how do you know if your driveway has been poorly graded? Here are the most common warning signs property owners should watch out for.
Standing Water After Rain
One of the clearest indicators of poor grading is puddles or pooling water on the surface after rainfall. Water that doesn’t drain away properly can:
- Weaken the asphalt or bitumen
- Lead to potholes or soft spots
- Encourage weed growth
- Cause slippery surfaces
Driveways should be built with a slight slope to allow water to flow away — either toward the street, a drain, or a soakwell.
Erosion at the Edges
If you notice material being washed away from the edges of your driveway, it’s likely that surface runoff is not being managed correctly. This erosion can expose the base layer, weaken the structure, and eventually lead to cracking or edge collapse.
Visible Cracks or Depressions
Poor grading often causes water to collect in certain areas, which over time can lead to cracking, warping or rutting. These depressions may start small but grow quickly as the surface weakens under repeated pressure and water infiltration.
Look for:
- Longitudinal cracks running along the length of the driveway
- Alligator cracking (a pattern resembling reptile skin)
- Sagging areas or surface undulations
Muddy or Soft Areas Adjacent to the Driveway
If your driveway has no kerbing or proper runoff controls, excess water can flood adjacent lawns, garden beds or gravel sections, turning them into muddy hazards. This not only affects aesthetics but may also contribute to damage at the driveway edges.
Washed-Out Base Material
Another red flag is the appearance of loose gravel or crushed rock near low spots or along the sides of the driveway. This often means that the base layer is being compromised due to poor water flow, causing the top layer to become unstable or lose cohesion.
Ice Patches in Winter
For areas that experience colder months, ice can easily form in low spots where water collects and freezes overnight. This can lead to dangerous slip hazards and further damage as the water expands and contracts beneath the surface.
Drainage Issues Near Buildings
If your driveway slopes toward your garage, shed or home, water can pool at the base of these structures. This creates a risk of:
- Moisture damage to building foundations
- Flooding in low-lying areas
- Rising damp or mould inside walls
The driveway should always be graded to guide water away from buildings and into safe drainage zones.
Why Grading Matters for Longevity
Proper driveway grading ensures:
- Water drainage is efficient and predictable
- Surface wear is evenly distributed
- Structural stability is maintained over time
- Maintenance costs are minimised
Ignoring grading issues can result in the need for full resurfacing or base reconstruction far sooner than expected.
